* Add ftpd.conf(5) directive `advertise'; change the address that is
advertised to the client for PASV transfers. this may be useful in
certain firewall/NAT environments.
Feature requested in [bin/9606] by Scott Presnell.
* Add -X option; syslog wu-ftpd style xferlog messages, prefixed with
`xferlog: '. An example line from syslog (wrapped):
Dec 16 18:50:24 odysseus ftpd[571]: xferlog: Sat Dec 16 18:50:24 2000
2 localhost 3747328 /pub/WLW2K601.EXE b _ o a lukem@ FTP 0 * c
These messages can be converted to a wu-ftpd style xferlog file
suitable for parsing with third-party tools with something like:
grep 'xferlog: ' /var/log/xferlog | \
sed -e 's/^.*xferlog: //' >wuxferlog
The format is the same as the wu-ftpd xferlog entries (with the leading
syslog stuff), but different from the wu-ftpd syslogged xferlog entries
because the latter is not as easy to convert into the standard xferlog
file format.
The choice to only syslog the xferlog messages rather than append to
a /var/log/xferlog file was made because the latter doesn't work to
well in the situation where the logfile is rotated and compressed and
a long-running ftpd still has a file-descriptor to the now nonexistant
xferlog file, and the log message will then get lost.

Fixes:
* In ftpd(8), clarify the -a and -c options.
* More clarifications in ftpd.conf(5).
* Ensure that all ftpd.conf commands set a parameter back to sane defaults
if an argument of `none' or bad settings are given.
* Support the `chroot' directive for `REAL' users too (for consistency).
* For `GUEST' users, store the supplied password in pw->pw_passwd for use
later in the xferlog.
* If show_chdir_messages() is given a code of -1, flush the cache of
visited directories. Invoke show_chdir_messages(-1) in end_login().
* Only syslog session stats if logging is requested.
* Rename logcmd() -> logxfer(), and dolog() -> logremotehost().
* Use cprintf() instead of fprintf() where appropriate.
* Minor KNF, and make a couple of functions static that were declared static.
in porting to other systems.
- don't syslog() or setproctitle() "ACCT" lines (as per "PASS")
- replace #ifdef HASSETPROCTITLE with #if HAVE_SETPROCTITLE, and set the
latter #ifdef BSD4_4
- don't compile in internal `ls' #ifdef NO_INTERNAL_LS. will need Makefile
support if this is to be used on NetBSD.
avoiding needless looping (possibly infinite looping) on certain kinds of
errors.
Get rid of erroneous free() in error return from add_segment.
Patch from Jesse Off <joff@gci-net.com> (PR #11547).
maxfilesize set the maximum size of uploaded files
sanenames if set, only permit uploaded filenames that contain
characters from the set "-+,._A-Za-z0-9" and that
don't start with `.'
- new/changed command line options:
-e emailaddr define email address for %E (see below)
-P dataport use dataport as the dataport (instead of ctrlport-1)
-q use pid files to count users [default]
-Q don't use pid files to count users
-u write entries to utmp
-U don't write entries to utmp [default]
-w write entries to wtmp [default]
-W don't write entries to wtmp
NOTE: -U used to mean `write utmp entries'. Its meaning has changed
so that it's orthogonal with -q/-Q and -w/-W. This isn't
considered a major problem, because using -U isn't going to
enable something you don't want, but will disable something
you did want (which is safer).
- new display file escape sequences:
%E email address
%s literal `s' if the previous %M or %N wasn't ``1''.
%S literal `S' if the previous %M or %N wasn't ``1''.
- expand the description of building ~ftp/incoming to cover the
appropriate ftpd.conf(5) directives (which are defaults, but it pays
to explicitly explain them)
- replace strsuftoi() with strsuftoll(), which returns a long long if
supported, otherwise a long
- rework the way that check_modify and check_upload are done in the yacc
parser; they're merged into a common check_write() function which is
called explicitly
- merge all ftpclass `flag variables' into a single bitfield-based flag element
- move various common bits of parse_conf() into a couple of macros
- clean up some comments
* replace union sockunion {} with struct sockinet {}, and modify the code
accordingly. this is possibly more portable, as it doesn't rely upon
the structure alignment within the union for our own stuff. uses local
su_len unless HAVE_SOCKADDR_SA_LEN is defined (set ifdef BSD4_4)
(XXX: haven't tested the ipv6 stuff)
* always use getaddrinfo() and getnameinfo() instead of maintaining two code
paths. (lukemftpd will provide replacements for these on older systems)
* use lockf() instead of open(.., O_EXLOCK) to lock the pid file
* minor KNF
* clean up long long support: create helper #defines and use as appropriate:
#define NO_LONG_LONG ! NO_LONG_LONG
